Solution Overview

Problem

Cosmetic care products face challenges in protecting hair from the detrimental effects of air pollutants and chemical stress, which lead to damage such as reduced shine, grip, and fading of hair color, as well as the need for specialized care due to changing consumer demands and frequent chemical exposure.

Innovation Solution

A cosmetic composition comprising an organic silicon compound with one to three silicon atoms and a sulfated or sulfonated fatty acid ester is used to treat keratinous materials like hair, providing a protective film and enhanced care by combining (3-aminopropyl)triethoxysilane or similar compounds with sulfated fatty acid triglycerides.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If organosilicon compounds with hydroxy groups or hydrolyzable groups are used, then a protective film is formed on the keratinous material, but the compounds are reactive substances that hydrolyze or oligomerize or polymerize in the presence of water

Engineering Contradiction:

Improveprotective effectVSAvoidreactivity control

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces water-soluble polymers as intermediary substances that mediate between the reactive organosilicon compounds and water. These polymers have hydrolyzable groups that can interact with both the silane compounds and water, controlling the hydrolysis and polymerization processes to form protective films while managing the reactivity issues

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates composite systems combining organosilicon compounds with water-soluble polymers having specific functional groups. This composite approach allows the protective film-forming capability of silanes to be combined with the water-solubility and controlled reactivity of the polymer systems, achieving both protection and controlled reaction kinetics

Inventive Principle:

Principle #40Composite materials

2Adaptability or versatility

If frequent chemical exposure is applied to achieve changing hair texture demands, then consumer hair texture requirements are met, but the hair suffers from recurring chemical stress and damage

Engineering Contradiction:

Improvehair texture versatilityVSAvoidchemical stress damage

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary protective measures by forming protective films on the hair before chemical treatments. The organosilicon compounds create a protective barrier that is applied prior to chemical stressors, preventing direct contact between chemicals and the hair shaft, thereby reducing damage while allowing texture changes

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent converts the harmful effect of chemical stress into a benefit by using the chemical treatment process itself to activate the protective film. The hydrolysis and polymerization of the organosilicon compounds are triggered by the chemical environment of hair treatments, transforming the potentially harmful chemical exposure into the activation mechanism for the protective barrier

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
